Word maps and spectra of random graph lifts
We study here the spectra of random lifts of graphs. Let G be a finite connected graph, and let the infinite tree T be its universal cover space. If λ1 and ρ are the spectral ...

Model-Based Tests for Access Control Policies
We present a model-based approach to testing access control requirements. By using combinatorial testing, we first automatically generate test cases from and without access contro...

2-Source Extractors under Computational Assumptions and Cryptography with Defective Randomness
Abstract— We show how to efficiently extract truly random bits from two independent sources of linear min-entropy, under a computational assumption. The assumption we rely on is...

Near-Optimal Conversion of Hardness into Pseudo-Randomness
Various efforts ([?, ?, ?]) have been made in recent years to derandomize probabilistic algorithms using the complexity theoretic assumption that there exists a problem in E = dti...
